There are many reasons why actors are deliberately uncredited, but usually it's because they don't want to be seen taken a minor part when they are major stars. This isn't ego: it's money -- the studios will try to lowball their next starring role by pointing out they were willing to take less for their last role in small supporting part they liked.

It is always the actor's choice -- he'll raise a stink otherwise.
